History
KDNA and easy listening
The 102.5 frequency in St. Louis had originally been the home of listener-supported free form KDNA from 1969 to 1972. KDNA was a non-commercial station, supported by listener donations, yet it broadcast on a commercial frequency. In 1972, it relocated to the non-commercial part of the FM dial, and became KDHX at 88.1 MHz.
Heftel Broadcasting paid for the frequency, and in June 1973, it put KEZK on the air.

Why this record matters
The phrase “adult contemporary radio station in St. Louis” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Jul 29, 2026. The linked authority identifier is Q6328813. Authority coordinates are 38.573, -90.325. 3 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1969, 1972 and 1973.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
